Topic: Shop roasters (14 msgs / 480 lines)
1) From: Cory Creighton
Hi all,
Does anyone have any feedback on the Diedrich 2.5 kilo roaster or the 3
kilo from US Roaster Corp?  I've been looking at both and figured there is
probably some people on this list who had experience with one or both.  Any
thoughts on either roaster would be greatly appreciated.
Roast on!

IMO Dietrich fine quality roaster BUT over state their capacity (with any
profile control). OTH USRC under states their roaster capacity. Been using
USRC 3k (with profile controller) for 5 1/2 years, consistent reliable work
horse capable of excellent roasts. My production roasts are to "yield" 6lb
post roast which means 6.9 to 7.2lb greens (depending on green and profile)
no problem. Most of my roast profiles run 14 to 15:30 depending on profile
etc. For fun early on tested the real max capacity of my little mule and did
a 10lb greens batch. Ran flat out and got to LFC (first touch of 2nd) in 20
minutes. About the same length of time a Dietrich will run at rated capacity
not 50% OVER rated capacity. Oh AND discovered that 10lb greens size batch
was a bit too big for cooling tray! It is a 3k = 6.6lb rated roaster after
all. :-)
Dietrich touts their "fuel efficiency". True at the expense of actual batch
size. I'm still running more expensive propane (vs. natural gas) and my
average propane cost per lb post roast is ~5 cents, break the bank! Did the
math and would take me easily 20 years in fuel savings to pay for the cost
to have existing natural gas line tapped (for furnace).

Correction Diedrich batch size (likely) not as highly over stated as it once
was. They used to call their (now called) 2.5k a 3k... The old Diedrich 3k
is was I have some limited experience roasting on...

MMC, how much was that roaster? I have friend at work that has been using 3
hottops and runs thru a $1000 in green to seel at work.
Obviously he needs a bigger roaster (even if it does cut into Scotch time;
he drinks it while roasting).

I'll let you know how the learning curve is in a few weeks Corey.  My USR 3
kilo should be delivered by the second week of sept.  It's ready to ship
now, but I'm not quite ready for it yet, lol!  I'm heading to OK city next
week for a day of training.  The roaster will ship the day after training.
 it's nice to be able to get trained on my roaster!
 :)
I'm guessing I will have to learn to roast all over again, but hopefully
some of what I've learned on the Quest M3 will carry over, or at least I
will be  able to adapt the principles.

Ben, 6 years ago when I bought mine a full manual USRC was $8k, mine was
$12.5k with PLC profile controller including auto-dump. Can of course also
roast full manual but why? The art is dialing in a profile for a given bean
not then wasting time twiddling dials the same way batch after batch after
batch. (Of course monitoring automated profiles and adjusting as/when
needed.) A trained monkey can adjust flame and airflow to follow an already
determined profile. That additional $4.5k was money very well spent allowing
multitasking which equals greater productivity.
Sounds like Rick can tell you what they're going for now. :-)
Congratulations! You will of course have a learning curve getting to know
how to control and best use your new tool. That's what it is, a roasting
tool. A very capable roasting tool in my experience. Roasting principles are
roasting principles. It's up to you to continue learning and apply them, the
roaster won't do it for you the Roaster!

Mike,
How do you monitor your tanks using propane?  do you use a two tank system?

MiKe, how does it track your template profile? Does it use several target
points or adjust all along the way following a profile curve.

My PLC controller programmed for 15sec interval set points...
Propane tank ?: use 2 but not on auto switch over currently. Manually keep
track of batch count, switch tank (20lb/5gal "standard/common" size) between
40-50 batches, have gone as many as 53 batches but as tank gets lower
pressure decreases a bit so usually swap by 45. Have never run out during a
roast...a good thing! (was sweating it a bit that time ran 53 batches before
tank swap but had forgotten to fill the other tank and wanted to finish the
days roast session :-)

Thanks miKe!
It's $350 for me to put in a nat gas line, so I'm leaning towards the
propane but wondered how it was working out for you.
45 batches is a pretty good amount of roasting. particularly for the size
of my operation starting out.

Eh 45 batches only equivalent to ~2.39 "bags-o-greens". I currently usually
swap tanks at least once a week sometimes two. :-) The constant tank
refilling/swapping can be a PIA, especially leading into Christmas roasting
cranking 200 or so batches in a couple weeks, but since actively looking for
a different Roastery location will continue as is for now.
BTW my roast avg. batch count per tank is for my usual 6 to 15 batch
sessions. (Most batches in a session so far 26, took 7.5 hours including
pre-heat for 156 lb post roast.) If doing a bunch of small run sessions
actual "roast" batches will be lower since equivalent of about a batch worth
of fuel is used every pre-heat.
Good luck (luck = preparation + opportunity + guts + never giving up no
matter what) in what sounds like turning Professional Roaster!

Thanks for the good wishes miKe!
I look forward to reaching a production level that requires changing tanks
weekly!
I've got plenty of "opportunity + guts + never giving up no
matter what"  but a little low on the preparation for now.
 I've been preparing for 5 years, but the final decision was rather rushed
(after 5 years?, well that's another story and will be overcome :)
